Add numbers in a list relative to a given index

I'd like to know if there's a bult-in function in Python to add the elements of a list relative to a specific index. Let me explain. Say I have a list list = [1,2,3,4,5] . I want to be able to add the numbers of lets say list[0:2]. In this case the answer would be 6.

I know for a fact that I could do it with a simple loop but I would prefer a one liner, if possible.

Anyway, thanks in advance!

Just sum(your_list[0:2]). This is easy and very fast. BTW, avoid calling your list list because it will shadow the built-in list function.
